Low MOQ Metal Dome Membrane Switch, metal dome tactile switch OEM
Membrane Switches are structurally divided into two categories: tactile and non-tactile. Non-tactile type usually has two types of non-tactile structure: flat type non-tactile type and convex key frame (in some cases convex blind spot). The non-tactile Membrane Switch does not require hand feel, but requires high sensitivity. It is turned on when touched, but cannot be short-circuited when the button is not pressed. Therefore, a reasonable isolation point should be added on the lower circuit key body.
Membrane switch is an operating system that integrates key functions, indicating elements and instrument panels. It consists of four parts: panel, upper circuit, isolation layer and lower circuit. When the membrane switch is pressed, the contacts of the upper circuit are deformed downward, and are in contact with the pole plate of the lower circuit. After the finger is released, the contacts of the upper circuit bounce back, the circuit is disconnected, and the circuit triggers a signal.The membrane switch has strict structure, beautiful appearance and good sealing performance.
We are a Membrane Switches manufacturer engaged in Graphic Overlay,Membrane Panels, Soft Circuits, Silicone Rubber Keyboard, LED , LGF Silicone Rubber Keypad,. All kinds of customization, welcome to come to consult.
